SATEL SLIM-R-DUAL-LUNA Ceiling Dual Motion Detector (PIR + Microwave, Anti-masking)

Imagine a discreet ceiling-mounted sensor that watches over a modern office lobby, where every movement matters and false alarms are not an option. The SATEL SLIM-R-DUAL-LUNA combines passive infrared and microwave detection in a slim, unobtrusive housing, delivering reliable intrusion detection for professional security systems. Its dual technology verifies motion using two independent channels, dramatically reducing false triggers caused by pets, drafts, or moving objects.

Key specifications

• Detection method: Dual technology – PIR and microwave (24.125 GHz)
• Mounting type: Ceiling, recommended height 2.4 to 4 m
• Detection range: up to 16 m diameter at 4 m height
• Power supply: 12 V DC ±15%, standby current 12 mA, max 17 mA
• Alarm and tamper outputs: NC relays rated 40 mA / 24 V DC
• Anti-masking: microwave-based, detects attempts to cover the sensor
• Adjustable sensitivity for PIR and microwave independently
• Supports EOL resistors (2EOL/NC) and alarm memory
• LED indicators for alarm, tamper, and power status
• Environmental class II, security grade 2 (EN 50131-2-4)
• Operating temperature: -10°C to +55°C

Why choose it

This detector is engineered for demanding commercial and residential installations where both performance and aesthetics matter. Its slim profile blends seamlessly into ceilings, while the dual-technology verification ensures high catch performance with minimal false alarms. The built-in anti-masking feature adds an extra layer of security by alerting the system if someone tries to block the sensor. With independent sensitivity adjustments, installers can fine-tune detection to match the environment, reducing nuisance activations in challenging spaces.

Ideal use cases

• Office buildings, retail stores, and showrooms requiring discreet ceiling coverage
• High-security areas where anti-masking is essential
• Rooms with high ceilings up to 4 meters, such as lobbies, warehouses, and atriums
• Integration with SATEL alarm control panels supporting NC and EOL configurations

Good to know

The SLIM-R-DUAL-LUNA is a Grade 2 security device, suitable for medium-risk applications. It operates reliably in a wide temperature range and meets environmental class II standards. Installation is straightforward with ceiling mounting, and the detector's LED indicators simplify walk-testing and diagnostics. For optimal performance, mount at the recommended height and adjust PIR and microwave sensitivities according to the room's layout and potential sources of interference.
